The “octagonal foot” is a skeletal deformity of the lower limbs, divided into “external octagonal foot” (i.e. “X” shaped leg) and “internal octagonal foot” (i.e. “O” shaped leg). “(i.e. “O” shaped leg) two kinds. Generally, “outwardly shaped feet” are mostly seen in children who are learning to walk, while “inwardly shaped feet” are mostly seen in children who can already walk. The main reason for the “octagonal feet” is that children are “calcium deficient” (i.e., vitamin D deficiency rickets), when children’s bones become soft due to reduced calcium deposits and excessive cartilage proliferation, plus children have begun to stand and learn to walk, the softened lower limb bones are like young branches Like a young branch can not withstand the pressure of the body, so gradually bending deformation and the formation of the “eight. Explanation of causes 1, congenital genetic factors. If one of the parents has an inward or outwardly shaped foot, the child is likely to be one of them. 2. Insufficient strength of the leg and ankle joint. In sprinting, this phenomenon is particularly obvious. Some students desperately back pedal in order to run fast, and both feet involuntarily turn inward or outward. 3, did not master the correct posture of running or walking. 4, the influence of the living environment. 5, the students who have participated in the basic dance training, there are also external eight feet. 6, the formation of the cause of the eight-footed also from the beginning of toddler toddler talk. Some mothers take the early and late walking to measure the baby’s intelligence or not, so they are eager to let the baby learn to walk. Because the baby’s body is in the developmental stage, the foot strength is not enough, toddler and standing, the feet will naturally separate, so that the area of the soles of the feet to increase the strength to prevent falls, resulting in the natural separation of the feet posture. 7, let the baby during the toddler wear hard leather shoes is not scientific. Because of the soft foot bones and weak ankle strength, leather shoes are hard and heavy, so babies have a feeling of “not being able to carry” the shoes, and over time, they distort the gait. Remind mothers, toddler period, wear cloth shoes is the best choice. 8, due to the lack of calcium in the baby’s body, the calcium content of the bones themselves is low, coupled with the pressure on the bones when walking and standing, it is easy to make the bilateral iliac joints appear outward, the formation of “outward eight” feet. Therefore, the mother should pay attention to, do not let the calcium deficient baby early toddler, timely supply of children with adequate protein, calcium and vitamin D-rich food, go outdoors more sunshine helps calcium absorption, prevent rickets. 9, soccer players, due to prolonged knee and ankle joint wear and tear is also an important part of the cause of the ectopia. 10, other external causes. Note In our daily study, life, once found inside or outside the octagonal foot, should pay attention to timely correction, if the parents of a party itself is inside or outside the octagonal foot, must pay close attention to the child’s walking, running posture, found the problem, timely correction. Basic exercise 1, first of all, to strengthen the legs, foot arch and ankle strength exercises. For example: in situ feet together upward lifting stirrups exercises, in situ or marching high leg running exercises (amplitude, speed mastered by themselves). 2, master the correct technical movements of running, and under the guidance of the teacher, repeatedly practice the correct technical movements, so that the movement to achieve power stereotypes. 3, due to the influence of the living environment and produce internal and external octagonal feet of students, pay attention to the development of the corresponding muscles. For example, do some exercises of internal rotation, external rotation of the thigh and hook the back of the foot to do by internal rotation, external rotation of the ankle. 4, due to habitual movements and the formation of the external eight feet, in ordinary daily life, should be consciously correct the habits of the external eight feet; and internal eight feet, can participate in the basic dance training. Such as doing leg press exercises: one foot support, the other foot straight in about 80 cm high pole for the front leg press, required to be pressed leg toe external rotation. 5, the use of professional Lixing Tiandi foot aids for correction, after a certain period of orthopedic can achieve results. 6, correction of body shape, standing and walking with the correct posture, not only can effectively solve the problem of the external eight, but also solve the problem of hunchback. In short, regardless of internal and external octagonal feet, as long as the conscious orthopedic and various exercises, long-term adherence to the correct walking and running posture, you can certainly correct. Corrective methods The purpose of corrective exercises is to strengthen the leg exercises, so that the strength of the inner thigh group of muscles is strengthened and the calf triceps are often hung to the exercise. 1, sitting on a chair, both hands back support, ankle at the clip an object (can be changed from thick to thin), the two knees together, and then straight leg up to the level, and then drop 15 a 20 times X 3 groups. 2, both legs bent knees sitting on the ground, knees out, feet relative, both arms bent, both hands on the inside of the knee, force down the knee joint, to the maximum hold 2 seconds, and then restore. 3, straight-legged sitting, two hands behind the body to support the ground, the two knees between a soft object (such as a small ball), with a rubber band to tie the ankle joint, practice for 5 minutes, requiring the calf to clamp objects with force. 4, two legs open into two, two knees as far apart as possible to the sides, chest and back, bend the knee half group, slowly lift the heel, and then drop, repeatedly lift and drop the heel, until the calf has a sense of soreness. 5.Kick the shuttlecock to the inside of the lower leg, alternating between the two legs. If the inner ankle spacing is 3-6cm, it can be treated by non-stressful surgery: massage the outer thigh muscles during the day, and make the two ankles and femoral condyles close together at night after the child sleeps and use a bandage or splint to gradually correct; supplement calcium and vitamin D, and get more sunlight. The inner ankle spacing in 6-9cm, can help a bunch of surgical treatment: 1, lateral epiphyseal block of the knee 2, femoral condylar osteotomy, you can contact with orthopedic physician courage consultation like correction methods out (including surgery).
